Troth your right on the money.
I wrote a reply to Len this morning , but our internet provider locked up, I wonder if the administrators here had anything to do with that. Just kidding.
I suggested to Len, that he call Winnebago Customer Service, not Customer Relations, and ask to talk to a tech. They can advise him about the wiring and mechanicals in the roof. Then call Fantastic Vent and talk to my good friend, Boo Berretta the gerru of installations and upgrades.
In my opinion, I think Len would money ahead, if he'd replace the vent fan in the bathroom with Fantastic Vents top of the line unit that has all the features. Fantastic Vent fans in the bathroom can handle his coach without any problem and he'll save himself a lot of extra work and possibily some trouble.

Remember, don't put any covers over your Fantasic Vent Fans, they cut the performance by 35%. Ask Bob about that.
